1， 文件 project.properties 修改：

target=android-14
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

必须这个顺序 。

2，proguard-project.txt

注意排除使用反射的源码。

# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

-dontskipnonpubliclibraryclassmembers
-dontshrink
-dontoptimize
-dontwarn com.google.android.maps.**
-dontwarn android.webkit.WebView
-dontwarn com.umeng.**
-dontwarn com.tencent.weibo.sdk.**
-dontwarn com.baidu.mapapi.**

-libraryjars libs/SocialSDK_QQZone_2.jar

-keep enum com.facebook.**
-keepattributes Exceptions,InnerClasses,Signature
-keepattributes *Annotation*
-keepattributes SourceFile,LineNumberTable

-keep public interface com.facebook.**
-keep public interface com.tencent.**
-keep public interface com.umeng.socialize.**
-keep public interface com.umeng.socialize.sensor.**
-keep public interface com.umeng.scrshot.**

-keep public class com.umeng.socialize.* {*;}
-keep public class javax.**
-keep public class android.webkit.**

-keep class com.facebook.**
-keep class com.umeng.scrshot.**
-keep public class com.tencent.** {*;}
-keep class com.umeng.socialize.sensor.**

-keep class com.tencent.mm.sdk.modelmsg.WXMediaMessage {*;}

-keep class com.tencent.mm.sdk.modelmsg.** implements com.tencent.mm.sdk.modelmsg.WXMediaMessage$IMediaObject {*;}

-keep class im.yixin.sdk.api.YXMessage {*;}
-keep class im.yixin.sdk.api.** implements im.yixin.sdk.api.YXMessage$YXMessageData{*;}

-keep public class [your package].R$*{
public static final int *;
}

-libraryjars libs/afinal.jar
-dontwarn net.tsz.afinal.**
-keep class net.tsz.afinal.** { *; }
-keep public class * extends net.tsz.afinal.**
-keep public interface net.tsz.afinal.** {*;}
-keepattributes Signature
-keepattributes *Annotation*
-keepclasseswithmembers class use.reflection.class.entity.** {
<fields>;

}

-libraryjars libs/baidumapapi_v3_2_0.jar
-keep class com.baidu.** { *; }
-keep class vi.com.gdi.bgl.android.**{*;}

-keep class your.package.class.** { *; }

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
# public *;
#}

3，用android tools export signed package才会被混淆

4，百度地图记得用申请的证书文件。

android 通过eclipse混淆代码 打包 + proguard 总结

(2013-04-12 16:39:25)

proguard.config=proguard.cfg

Eclipse会通过此配置在工程目录生成 proguard.cfg 文件

2 . 生成keystore (如已有可直接利用)

按照下面的命令行 在D:\Program Files\Java\jdk1.6.0_07\bin>目录下，输入keytool -genkey -alias android.keystore -keyalg RSA -validity 100000 -keystore android.keystore

参数意义：-validity主要是证书的有效期，写100000天；空格，退格键 都算密码。

命令执行后会在D:\Program Files\Java\jdk1.6.0_07\bin>目录下生成 android.keystore文件。

3. 在Eclipce的操作

File -> Export -> Export Android Application -> Select project -> Using the existing keystore , and input password -> select the destination APK file

经过混淆后的源代码，原先的类名和方法名会被类似a,b,c。。。的字符所替换，混淆的原理其实也就是类名和方法名的映射。
